Mild steel is a type of low carbon steel. Carbon steels are metals that contain a small percentage of carbon (max 2.1%) which enhances the properties of pure iron. The carbon content varies depending on the requirements for the steel. Low carbon steels contain carbon in the range of 0.05 to 0.25 percent. There are different grades of mild steel.

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. About 98% of the mined iron ore is used to make steel either by the blast furnace—basic oxygen furnace (BF-BOF) route—or through the electric arc furnace (EAF) route. The majority of world crude steel is made from the BF-BOF route.

12%The comminution process based on HPGR generates a higher fines proportion compared with the ball mill circuit by breaking down the minerals due to the pressure applied over the particles and to a greater extent owing to friction and shear forces acting among the particles in the particle bed [ 1, 11 ].

resistors can be connected to the rotor circuit, which improves the self-starting performance of the motor fed from three-phase grid with fixed frequency (see also Figure 7). A rotating magnetic field is produced by the stator windings, which are connected to the grid or an inverter. As long as the rotating speed is not equal to the speed

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Each mill measures about 12 metres in diameter and has an internal volume of 1,220 cubic metres. As the AG mill turns, the ore crushes against itself and breaks apart. From the AG mills, the ore travels to the primary magnetic separators where the iron is drawn away from the waste material before it's screened and fed into the ball mills.
